GSM MAP Service Framework <ul><li>The GSM entities communicate with each other to carry out some service, through MAP dialogues by invoking one of four MAP primitives: </li></ul><ul><li>REQUEST </li></ul><ul><li>INDICATION </li></ul><ul><li>RESPONSE </li></ul><ul><li>CONFIRM </li></ul>

11.
The Short Message Service <ul><li>Not requiring the end-to-end establishment of a traffic path </li></ul><ul><li>Asymmetric: Mobile Originating Short Message trasmission is considered as a different service from Mobile Terminating Short Message trasmission </li></ul><ul><li>Ultimate destination (identified by some field in the message) is relevant only for the user and the SMSC, not for the GSM infrastructure </li></ul>

JAIN Integrated Network APIs for the Java platform The objective of the JAIN initiative is to create an open value chain from 3rd-party service providers, facility-based service providers, telecom providers, and network equipment providers to telecom, consumer and computer equipment manufactures <ul><li>wireline (PSTN), </li></ul><ul><li>wireless (PLMN) and </li></ul><ul><li>packet based (IP and ATM) networks </li></ul>The JAIN initiative wants to integrate: by providing a new level of abstraction

19.
Business Drivers and Industry Goals The JAIN initiative takes the telecommunications/Internet market from many proprietary closed systems to a single open environment able to host a large variety of services making next generation telecom application development faster, simpler and less expensive <ul><li>Portability: Write Once Run Anywhere </li></ul><ul><li>Network Convergence: Any network !!! </li></ul><ul><li>Secure Network Access </li></ul>The JAIN initiative brings:

20.
The JAIN initiative is divided in two areas of development <ul><li>The Protocol API Specification </li></ul><ul><li>specify interfaces to wireline, wireless and IP signaling prtocols </li></ul><ul><li>The Application API Specifications </li></ul><ul><li>address the APIs required for service creation within a JAVA framework spanning across all protocols covered by the Protocol API Specification </li></ul>

28.
JAIN for MAP The first version of the JAIN MAP API will include a subset of all capabilities of the MAP protocol Functionalities to be supported : <ul><li>Short Message Service (SMS) </li></ul><ul><li>User to service data transfer (Unstructured Supplementary Service Data) </li></ul><ul><li>Subscriber Information (Any Time Interrogation) </li></ul><ul><li>Location Service and Emergency Location Information Delivery </li></ul>
